CSS to Tailwind Converter
Migrating a project to Tailwind can be painful when you have years of legacy CSS. This CSS to Tailwind converter helps you move faster by turning common declarations into the closest Tailwind utility classes it can find. Paste a rule like .card { padding: 16px; border-radius: 12px; } and get a class string you can drop into a class attribute. When a value does not match the Tailwind scale, the tool can emit arbitrary values like p-[18px] to preserve pixel-perfect layouts. It also lists declarations it cannot translate, so you can decide whether to keep custom CSS, add a plugin, or refactor the component. All conversion runs in your browser for privacy, which is helpful when your CSS includes internal design tokens or proprietary component names. Method details for CSS to Tailwind Converter: Processing follows explicit developer-facing rules for api payload shape, json/yaml structure, schema validation, and when applicable regex, hash, and checksum behavior.
Paste declarations or full rules. Selectors are ignored. Output is best-effort and may need small edits.

Why Tailwind Mapping Is Not 1:1
Tailwind is a constrained design system: Many utilities map to a scale. If your CSS uses values outside that scale, the closest match may be approximate. Arbitrary values like w-[372px] preserve exact sizes when needed.
CSS can be contextual: Some properties depend on layout context (for example, justify-content assumes display: flex). This tool focuses on common, direct mappings and surfaces anything it cannot safely translate.
Use this as a migration accelerator: You still get the final say. The goal is to cut repetitive work, not to produce perfect output for every edge case.
